My invention relates to a laundry machine and more particularly to a mounting of a drum and the driving motor therefor.

An object of my invention is to provide a resilient or elastic mounting for a laundry ma chine driving motor and an operatively associated drum.

A further object of my invention is to provide a laundry machine having a drum rotatively supported by a resiliently mounted driving mechanism. Another object of my invention is to provide a laundry machine having an intermediate bottom and a driving motor resiliently mounted through an aperture in such bottom with a drum attached to and supported by the motor shaft.

Other objects of I the invention will be pointed out specifically'in the course of the following description of a device embodying my invention, or will be apparent from such description.

The accompanying drawing is a sectional view illustrating a device embodying my invention in which I show a cylindrical laundry machine or centrifuge having a housing I and suitable studs or feet '2, preferably rubber or the like, for 'supporting the device.

A cover '3 having a funnel shaped charging opening therethrough may be positioned upon the housing. An inwardly extending intermediate bottom 4 having a centrally located aperture 20 is positioned within the housing I for supporting a driving motor 5, drum or motor shaft 6, and centrifuge drum 1, as hereinafter described. The motor 5 is preferably single phase having a high starting torque and is directly connected to the centrifuge drum 1 so as to run quietly. However, a set of transformation gears may, if desired, be locatedtherebetween.

, The motor 5, shaft 6 and drum lare elastically or res'liently supported upon the apertured intermediate bottom I, in this instance, by two spiral springs or resilient members ,8 and 9. The

springs 8 and 9 are preferably positioned concentrically about the motor 5 adjacent the aperture 20 with spring Bbeing located beneath and spring 9 being located above the intermediate or elastically mounted within the aperture in the intermediate bottom 4 and is free to rock,

vibrate or oscillate within the aperture without contacting the intermediate bottom 4.

- An upwardly extending collar or open-dish shaped member I2 is located about the aperture 20and motor 5 and is attached to the intermediate bottom 4. During the operation of the ma-' chine I and the rotation of drum 1 water or liquid is thrown out through apertures 22 in the lower portion of the drum 1. This liquid falls upon the intermediate bottom 4 and flows outwardly through the spout 23, as shown by arrow A. The member l2, by reason of its upstanding flange, prevents the water or liquid so thrown out of the drum 1 from reaching and flowing down through the aperture 20 in the intermediate bottom 4.

The bottom l3 of the drum I is arched upwardly, forming a spherical segmental space beneath and within the lower portion of the drum. A hub 1 I4 is rigidly attached to'the bottom I3 and affords means for vconnecting a drum 1 to the motor shaft 6. The hub l4, has in this instance, a. rectangular aperture cut therein which directly cooperates with the motor shaft 6 and prevents any relative rotative movement therebetween.

A braking disc I5 is rigidly attached -to the hub l4 and'is located within the upwardly arched bottom of drum 1. A braking block or mechanisni 2| cooperates with the disc ii for deceleratingthe drum 1 and motor 5 when it is desired to stop the drum. The braking block 2| is operated by means of cable It and a treadle l'l mounted upon the housing I. e

The hub l4, braking disc l5 and the upper end of the motor 5 extend upwardly within the spherical segmental space in the lower portion of the bottom 4. The ends of the springs adjacent the 7 which is rigidly attached to the upper bearing shield or end bell. The

motor 5 isthus flexibly drum I. This arrangement enables thestructure to utilize a minimum amount. of space,

which, in turn, may reduce the over-all height of the machine or-may permit the use of a larger drum with a housing of a given size.

It is to be understood thata plurality of other resilient members may be used in lieu of the springs 8 and 9 providing such. members. are located about the motor and are rigidly attached to the motor end bells and intermediate bottom 4 as hereinabove described.

Various modifications-may be made in the resilient laundering machine mounting embodying my invention without departing trom the spirit and scope thereof, and I-desire, therefore, that only such limitations shall be placed thereon as are imposed by the prior art and the appended claims.

I claim as my invention: 1. In a resilient support for a centrifuge structure including a basket and a motor tor driving second carrier members secured to axially spaced portions of the centrifuge structure, me for securing the end portions 01' the spring means to the first and second carrier members, respectively.

2. In a resilient support for a centrifuge structure having a basket and a motor for driving the same, the combination of first and second carrier members secured to the centrifuge structure and spaced axially thereof, a support arranged inter mediate said first and second carrier members. first and second helical springs axially spaced from each other and surrounding said motor. means for securing adjacent ends of the helical springs to said support, and means for securing the opposite ends of the helical springs to said carrier members.

3. Resilient means for supporting a centrifugal machine including a basket and a motor for rotating thesame, the combination of a. plate having an opening therein encompassing the motor, first and second disks secured to axially-spaced portions of the motor, and first and second helical springs encompassing the motor and aligned in substantially co-axial relation with respect to each other, adjacent ends of the springs bearing upon said support and the opposite ends of the springs engaging, respectively, said first and second disks.

d. In a resilient support for a centrifugal machine having a basket rotatable about a substantially vertical axis and a. motor co-axlally aligned with the basket for driving the same, the combination oi a supporting plate disposed in a substantially horizontal plane and having an opening formed in a central portion thereof for receiving said motor, first and second carrier members secured to axially-spaced portions of the motor, and first and second helical springs encompassing the motor, adjacent ends 01' the helical springs bearing upon said plate and opposite ends or the springs being engaged with the first and second carrier members respectively.
